Also, Horse Armor was more successful than you might think.

Out of the many changes made in Fallout 4, there's one aspect whose popularity surprised the development team at Bethesda the most.

Speaking with IGN, Fallout 4 director Todd Howard revealed he and the others had not necessarily expected the popularity of customizable workshops and bases.

"I think the Workshop stuff was the biggest surprise for us, in that...how many people gravitated toward it as its own game and are doing all sorts of crazy things with it," Howard said, adding the popularity had encouraged them to target further customization options in future DLC releases alongside traditional quest and challenge updates.

Regarding their future DLC plans, Howard compared it to the DLC previously released for The Elder Scrolls V: Skyrim and assured they would settle on prices for different offerings depending on the depth of the experience and content offered.

"In this first run [of DLC], Far Harbor is the largest. But, we kind of priced that based on what we've done before so you can look at Far Harbor and say 'Well, even though the land mass is bigger, it doesn't have as much content as Shivering Isles - which was $30- but it has more than Dawnguard, which was $20,'" he said.

"So, we look at what we've done before, and then once we've moved along with the content, say 'Okay, this is what we think it's worth.' But, right now, we have found all sizes and price points, [and] as long as it's good content, it's successful."

Howard later opened up about the success of The Elder Scrolls IV: Oblivion's infamous Horse Armor, the cosmetic DLC for mounts once criticized for not offering any particular benefits.

"[Horse Armor] was one of the most popular [DLC packs] we've done, believe it or not," he said, later observing the team abandoned the idea of cosmetic add-ons around the time they became more popular. "What's funny is, we went away from Horse Armor, and the rest of the industry has gone toward Horse Armor."
